Answer: The ovule’s structure is as follows: The ovule and the placenta are connected by a tiny structure called a funicle. The point at which the ovule’s body unites with the funicle is known as the hilum. Nucellus: The nucellus is the ovule’s body, which is made up of a mass of parenchymatous cells.
The female gametophyte, the ovule, develops inside the ovary from the placenta, a cushion-like structure. A stalk called a funicle connects it to the placenta. The nucellus is the nutritive tissue that is encased within the ovule. The outer and inner integuments encircle Nucellus. These integuments leave a micropyle, a tiny pore at the front end. The anterior end of the ovule is the micropyle, whereas the posterior end is the chalazal.
